(xminc-read-tfm :filename <xfm-file> :transform <tfm> )
This function imports linear transform from <xfm-file> -- MNI transform file with extension .xfm. This file must hold general transform consisting of just one linear transform. Transform <tfm> is a class-matrix44 object, and must exist. It will be populated with the 4x4 matrix read from the <xfm-file> and concatenated with the conversion matrix. The latter converts MINC coordinate system into skandha4 coordinate system.
